Technical data
Tab. A
(1)
Reference conditions: Ambient temperature 20°C - Gas temperature 15°C - Barometric pressure 1013 mbar - Altitude 0 m a.s.l.
(2)
Pressure at test point 7)(Fig. 4) with zero pressure in combustion chamber and at maximum burner output.
(3)
Sound pressure measured in manufacturer's combustion laboratory, with burner operating on test boiler and at maximum output.
The sound power is measured using the "Free Field" method, required by EN 15036 standard, and according to an “Accuracy: Category 3”
measurement, as described in EN ISO 3746.
